Why Zebras Don't Get Ulcers
by Robert M. Sapolsky
Sapolsky's classic on stress physiology: the stress response evolved for sprints from lions, and humans turn it on for mortgages and traffic, damaging heart, gut, immunity, memory and sleep. He is funny, rigorous and humane, and the final chapter on what actually helps, control, predictability, outlets, social support, is the practical payoff.
